Moment of Force (Torque) Converter

About This Tool

This Moment of Force Converter is an essential tool for mechanical engineers, physicists, and technicians. Moment of force, more commonly known as torque, is the rotational equivalent of linear force. It measures the tendency of a force to cause rotation around an axis. The base unit for all calculations is the newton meter (N·m), the standard SI unit.

From tightening a bolt to designing an engine, torque is a fundamental concept. This tool allows for easy conversion between the SI standard (newton meter) and imperial/customary units like the pound-force foot (lbf·ft), which is widely used in the automotive and manufacturing industries in the United States.

Tips & Features

• The Newton Meter Standard: All torque units are converted by relating them back to the newton meter (N·m). One newton meter is the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one meter long.
• Torque vs. Energy: The units for torque (N·m) are dimensionally the same as for energy (joules). However, they represent very different physical concepts. Torque is a vector quantity (force at a distance), while energy is a scalar quantity (capacity to do work). To avoid confusion, the unit 'joule' is typically not used for torque.
• Common Applications: Pound-force foot (lbf·ft) is the standard for torque wrench specifications and engine torque ratings in the U.S., while the newton meter (N·m) is the global standard in scientific and most automotive contexts.
